| 摘 要： | 根据热力学分析,提出从黑钨精矿硫酸分解得粗钨酸,直接从浸出波用2-乙基膦已基酸单2-乙基已酯萃取回收钪的新工艺.此工艺与前文提出的用盐酸分解黑钨精矿,直接从浸出液用二(2-乙基已基)磷酸萃取回收钪工艺一样,具有流程简单,回收率高,不消耗碱,一次浸出即可使钨与钪分离等优点.由于实现了“钨钪并收”,既改进了钨工艺流程,又回收了钪,从而改进了目前我国普遍采用的碱法提钨,从碱压法提钪的工艺流程.同时又克服了盐酸体系工艺中设备腐蚀严重,工作环境差的缺点.而且采用的钪萃取剂更为有效.

| Abstract: | In accordance with the thermodynamic analysis, a new method of extracting tungsten and scandium from the wolframite in sulfuric acid medium is reported . This method avoids the emergence of hydrochloric acid vapour and retains the advantages which are found in the technical process proposed by the author in his previous article. |
